Abstract: PURPOSE:To attain accurate and fast speed frequency switching by eliminating an error attended with normalized phase information in a frequency synthesizer implementing the phase comparison by the numerical arithmetic operation processing. CONSTITUTION:A reference signal output section composed of a reference oscillator 11, frequency dividers 12, 13 and an accumulator 14 outputs value resulting from a phase of a reference signal normalizing a phase of a reference signal by using maximum phase information for one period of the reference signal as a value mKN, where m, K, N are natural numbers and N is a value set to decide the oscillating frequency. A frequency division signal phase output section composed of a voltage controlled oscillator 15, a counter 16 and a sampling multiplier 17, etc., outputs a value resulting from the phase of a frequency division signal normalizing the phase of a reference signal by using maximum phase information as the value mKN. A reference signal phase output section uses a value accumulating sequentially a value mN for each period of 1/K of the period of the reference signal as phase information. The counter 16 of a modulo N counts an oscillation signal and a sampling multiplier multiplies the counted value with the value mK to obtain frequency division phase information.
